a few months ago i remember there being a glich in the google system which showed virtually all sites as potentially causing harm and i don't know whether it is this again or whether you have inadvertently uplaod a virus to your FTP server without realising it.
Google was not hacked, but instead had a DNS problem. For some readers the site was redirecting to the SoGoSearch page. That continues to fox me, and I plan to investigate further. All services have been restored. I find it amazing: Google is now as integrated in our lives as a phone company, or heaven forbid, TV networks. Multiple experts say that the screen grab I got was result of broswers not being able to resolve to Google.com, and instead stumbled upon google.com.net (com.net is the SoGoSearch website, and they have a wildcard match). Once Google’s DNS was restored, browsers stopped the appending, and started functioning normally.
"this site may damage your computer" seems as a warning for visitors as the site may not pass google's anti-virus filter.
